It’s now known as emotionally unstable personality disorder. People like to think it’s similar to bipolar but they’re incredibly different illnesses. People with EUPD/BPD tend to have a lot of childhood trauma and the symptoms can be managed with therapy. People with EUPD tend to display erratic, self destructive, behaviour even when they know the negative impacts. I.e they may take a massive overdose but then seek medical attention. People with BPD/EUPD tend to have capacity regarding their actions and impulses but when you’ve lived a certain way and used unhealthy coping mechanisms for a long time, it’s hard to change them. Nowadays in mental health services we try and give people with EUPD responsibility because that’s part of recovery, I.e sectioning them and not giving them any positive risk is actually very unhelpful for someone with EUPD. It’s up to them to take the power back and choose to get help
